To all whom it may concern;

Be-it known that I, ARTHUR K. TAYLOR, a citizen of the United States,and a residen of Baltimore, Maryland, have invented a new and usefulPlate Mounting, of which the following is a specification.

My invention relates to improvements in plate mountings for printingplates, such as electrotype plates. The objects of my invention are:first, to secure a light mounting which can be made in large size andyet be readily handled; second, to secure a mounting which will not warpand which will be influenced by moisture and temperature to a minimumdegree; third, to secure a mounting to which plates may be readilyattached and on which they can be attached in any position; fourth, tosecure a mounting that can be made the correct thickness all over, evento 1/1000 of an inch; fifth, to

' secure a mounting that can be easily repaired; and sixth, to secure amounting that will not be distorted because of unequal pressure when itis clamped to the bed of the press. 7

I attain these objects and other apparent advantages by the deviceillustrated in the accompanying drawings in which Fig. 1 is a plan viewof the plate mounting; Fig. 2 is a front elevation with the front partof the rim 6 removed. Fig. 3 is a partial crosssection on line 33 ofFig. 1, looking in the direction of the arrows. Fig. 4 is a perspectiveof one of the wooden blocks.

Similar numerals refer to similar parts throughout the several views.

The base 1 is made up of aluminum, steel or any other rigid, tenaciousmaterial. Square blocks of wood 2 are placed on the base, and attachedto it preferably by screws 3, the heads of which are countersunk in thebase as shown in Fig. 3. These wooden blocks may be made of severallayers of wood, the grain of each layer running in a direction differentfrom that of the other layers as shown in Fig. 3, so that the blockswill not warp in any direction. Fig. 4 shows a perspective view of oneof the blocks. These blocks are not placed in contact with each otherunder normal atmospheric conditions, thus allowing for swelling withoutbuckling and also allowing for ready replacement. The blocks arearranged so that theiredges are oblique to the edges of the base. Nearthe edges of the base,- pieces" of blocks are put" in to i-fill up thewhole'surface; Around these blocks.

and fastened preferably by screws 5 to the top of the base, is a metalrim 6 which makes a rigid member to fasten the clamps on the press to. pThis rim also preventsthe whole base from being distorted or bent byunequal pressure of the clamps of the press. Should any of these blocksbecome damaged, the damaged ones can be easily replaced at small expenseby others; also, should the base be uneven at places or should theblocks be too thin, paper or other material could be put under theblocks to build up that portion. The construction of the base is suchthat accurate height to paper, over its entire surface, may readily besecured. The oblique arrangement of the blocks is to guard against manyof the tacks for an electrotype falling on the juncture of two blocks,but should tacks be driven between blocks as at 7, no obstruction wouldbe met; the only result would be that the tacks would not hold soeffectively.

The electrotypes are tacked to this wooden surface, in any desiredposition on the mounting, several being shown in Fig. 1.

The use of the word blocks in the following claims does not limit me tothe use of square blocks; the blocks may be of any shape that willaccomplish the purposes set forth.

I claim as new and desire to secure by Letters Patent:

1. A plate mounting consisting of a rigid tenacious base, a plurality oflaminated wooden blocks, and means for independ- Irgntly attaching eachof said blocks to said ase.

2. A plate mounting consisting of a rigid tenacious base, a plurality ofadjacent laminated wooden blocks, and means for independently attachingeach of said blocks to said base.

3. A plate mounting consisting of a rigid tenacious base, a plurality ofadjacent laminated wooden blocks arranged with their edges oblique tothe edges of said base and means for independently attaching each ofsaid blocks to said base,

4. A plate mounting consisting of a rigid tenacious base and a pluralityof penetrable fibrous blocks substantially covering said base, saidblocks being so placed in relation to each other as to allow for theirperipheral expansion and contraction and means for independentlyattaching each of said blocks to said base.

5. A plate mounting consisting of a rigid tenacious base and a pluralityof'penetrable fibrous blocks substantially covering said base, saidblocks being so placed in relation to each other as to allow for theirperipheral expansion and contraction and means for independentlyattaching each of said blocks to said base, whereby the peripheralexpansion and contraction of one of the blocks. will not vary the fixedposition of any of the blocks.

6. A plate mounting consisting of a rigid tenacious base and a pluralityof penetrable fibrous blocks substantially covering said base and meansfor independently attaching each of said blocks to said base, Wherebythe peripheral expansion and contraction of one of. the blocks will notvary the fixed position of any of the blocks.
